[FR Doc. 2013–18564 Filed 7–31–13; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2013–0665; Directorate Identifier 2012–NM–082–AD] RIN 2120–AA64 Airworthiness Directives; Airbus Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for all Airbus Model A330–300 series airplanes and Model A340–200 and –300 series airplanes. This proposed AD was prompted by reports of corrosion found on certain trimmable horizontal stabilizer actuators (THSA), affecting the ballscrew lower splines between the tie bar and the screw-jack. This proposed AD would require repetitive detailed inspections for corrosion of certain THSAs, ballscrew integrity tests if necessary; and replacing any affected THSA with a serviceable or new and improved THSA, if necessary. We are proposing this AD to detect and correct corrosion of the THSAs, which could lead, in the case of ballscrew rupture, to the loss of transmission of THSA torque loads from the ballscrew to the tie-bar, prompting THSA blowback, and possibly resulting in loss of control of the airplane. DATES: We must receive comments on this proposed AD by September 16, 2013.

Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012–0061R1, dated November 30, 2012 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Some Trimmable Horizontal Stabilizer Actuators (THSA), Part Number (P/N) 47147– 500, have been found with corrosion, affecting the ballscrew lower splines between the tie bar and the screw-jack. The results of the technical investigations have identified that the corrosion was caused by a combination of: —Contact/friction between the tie bar and the inner surface of the ballscrew leading to the removal of Molykote (corrosion protection) at the level of the tie bar splines, —Humidity ingress initiating surface oxidation starting from areas where Molykote is removed, and —Water retention in THSA lower part leading to corrosion spread out and to the creation of a brown deposit (iron oxide). The results of the technical investigations have also concluded that THSA P/N 47147– 500 and P/N 47147–700 ballscrews might be affected by this corrosion issue. THSA P/N 47147–400 ballscrews might be affected as well, but should no longer be in service, and modified into P/N 47147–500, as required by EASA AD 2010–0192 and EASA AD 2010–0193 [and as required by FAA AD 2005–07–04, Amendment 39–14028 (70 FR 16104, March 30, 2005)]. This condition, if not detected and corrected, may lead, in case of ballscrew rupture, to loss of transmission of THSA torque loads from the ballscrew to the tie-bar, prompting THSA blowback, possibly resulting in loss of control of the aeroplane. To correct this potential unsafe condition, EASA issued AD 2012–0061 to require repetitive [detailed] visual inspections of the ballscrew lower splines of THSA having P/N 47147–500 or P/N 47147–700 to detect corrosion and, depending on findings [ballscrew integrity tests], the accomplishment of applicable corrective actions [replacing the affected THSA with a serviceable or improved THSA]. Since that [EASA] AD [2012–0061] was issued, Airbus published new Service Bulletin (SB) A330–27–3194 or Airbus SB A340–27–4187 (Airbus modification 202802), which allow installation in service of an improved THSA P/N 47172–530. For the reasons described above, this [EASA] AD [2012–0061R1] is revised to specify that installation of THSA P/N 47172– E:\FR\FM\01AUP1.SGM 01AUP1 46544 Federal Register / Vol. 78, No. 148 / Thursday, August 1, 2013 / Proposed Rules 530 is an alternative (optional) terminating action to the repetitive inspections required by this AD. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Airbus has issued the following service information. • Airbus Mandatory Service Bulletin A330–27–3179, including Appendix 01, dated February 14, 2012. • Airbus Service Bulletin A330–27– 3182, dated February 14, 2012. • Airbus Service Bulletin A330–27– 3194, dated October 8, 2012. • Airbus Mandatory Service Bulletin A340–27–4175, including Appendix 01, dated February 14, 2012. • Airbus Service Bulletin A340–27– 4178, dated February 14, 2012. • Airbus Service Bulletin A340–27– 4187, dated October 8, 2012. Goodrich Actuation Systems has issued Service Bulletin 47147–27–18, dated February 17, 2012. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. emcdonald on DSK67QTVN1PROD with PROPOSALS Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 30 products of U.S. registry. We also estimate that it would take about 6 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $15,300, or $510 per product. In addition, we estimate that any necessary follow-on actions would take about 13 work-hours and require parts costing up to $722,556 for a cost of up to $723,661 per product. We have no way of determining the number of products that may need these actions. VerDate Mar<15>2010 16:23 Jul 31, 2013 Jkt 229001 Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. ‘‘Subtitle VII: Aviation Programs,’’ describes in more detail the scope of the Agency’s authority. We are issuing this rulemaking under the authority described in ‘‘Subtitle VII, Part A, Subpart III, Section 44701: General requirements.’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government. For the reasons discussed above, I certify this proposed regulation: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; 2. Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); 3. Will not affect intrastate aviation in Alaska; and 4. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

Background Over the past 20 years, contracting agencies have been gaining valuable experience with the design-build project delivery method for highway construction. In conjunction with this delivery method, some agencies have encouraged design-build proposers to submit ATCs as a way to encourage innovation, promote efficiency, reduce risk, accelerate project delivery schedules, and reduce project costs. An ATC is a request by a proposer to modify a contract requirement, specifically for that proposer’s use in the proposal process. The ATC must provide a solution that is equal or better to the requirements in the Request for Proposals (RFP) document. Proposers submit ATCs for the contracting agency’s conceptual approval during the procurement process. The contracting agency may conduct confidential meetings with each proposer to review and discuss that proposer’s ATCs. If the concept is approved by the contracting agency, the proposer may use the ATC in its technical and price proposal, thus providing the contracting agency with the potential for increased value at reduced costs. The FHWA’s current regulatory policy in 23 CFR Part 636 allows contracting agencies to use ATCs in their procurement process subject to two conditions: (1) The ATC must not E:\FR\FM\01AUP1.SGM 01AUP1

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all
Airbus Model A330-300 series airplanes and Model A340-200 and -300
series airplanes. This proposed AD was prompted by reports of corrosion
found on certain trimmable horizontal stabilizer actuators (THSA),
affecting the ballscrew lower splines between the tie bar and the
screw-jack. This proposed AD would require repetitive detailed
inspections for corrosion of certain THSAs, ballscrew integrity tests
if necessary; and replacing any affected THSA with a serviceable or new
and improved THSA, if necessary. We are proposing this AD to detect and
correct corrosion of the THSAs, which could lead, in the case of
ballscrew rupture, to the loss of transmission of THSA torque loads
from the ballscrew to the tie-bar, prompting THSA blowback, and
possibly resulting in loss of control of the airplane.

DATES: We must receive comments on this proposed AD by September 16,
2013.

ADDRESSES: You may send comments by any of the following methods:

Discussion

The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
Airworthiness Directive 2012-0061R1, dated November 30, 2012 (referred
to after this as ``the MCAI''), to correct an unsafe condition for the
specified products. The MCAI states:

Some Trimmable Horizontal Stabilizer Actuators (THSA), Part
Number (P/N) 47147-500, have been found with corrosion, affecting
the ballscrew lower splines between the tie bar and the screw-jack.
The results of the technical investigations have identified that
the corrosion was caused by a combination of:

--Contact/friction between the tie bar and the inner surface of the
ballscrew leading to the removal of Molykote (corrosion protection)
at the level of the tie bar splines,
--Humidity ingress initiating surface oxidation starting from areas
where Molykote is removed, and
--Water retention in THSA lower part leading to corrosion spread out
and to the creation of a brown deposit (iron oxide).

The results of the technical investigations have also concluded
that THSA P/N 47147-500 and P/N 47147-700 ballscrews might be
affected by this corrosion issue.
THSA P/N 47147-400 ballscrews might be affected as well, but
should no longer be in service, and modified into P/N 47147-500, as
required by EASA AD 2010-0192 and EASA AD 2010-0193 [and as required
by FAA AD 2005-07-04, Amendment 39-14028 (70 FR 16104, March 30,
2005)].
This condition, if not detected and corrected, may lead, in case
of ballscrew rupture, to loss of transmission of THSA torque loads
from the ballscrew to the tie-bar, prompting THSA blowback, possibly
resulting in loss of control of the aeroplane.
To correct this potential unsafe condition, EASA issued AD 2012-
0061 to require repetitive [detailed] visual inspections of the
ballscrew lower splines of THSA having P/N 47147-500 or P/N 47147-
700 to detect corrosion and, depending on findings [ballscrew
integrity tests], the accomplishment of applicable corrective
actions [replacing the affected THSA with a serviceable or improved
THSA].
Since that [EASA] AD [2012-0061] was issued, Airbus published
new Service Bulletin (SB) A330-27-3194 or Airbus SB A340-27-4187
(Airbus modification 202802), which allow installation in service of
an improved THSA P/N 47172-530.
For the reasons described above, this [EASA] AD [2012-0061R1] is
revised to specify that installation of THSA P/N 47172-

[[Page 46544]]

530 is an alternative (optional) terminating action to the
repetitive inspections required by this AD.

You may obtain further information by examining the MCAI in the AD
docket.

Appendix 01, dated February 14, 2012.
Airbus Service Bulletin A330-27-3182, dated February 14,
2012.
Airbus Service Bulletin A330-27-3194, dated October 8,
2012.
Airbus Mandatory Service Bulletin A340-27-4175, including
Appendix 01, dated February 14, 2012.
Airbus Service Bulletin A340-27-4178, dated February 14,
2012.
Airbus Service Bulletin A340-27-4187, dated October 8,
2012.
Goodrich Actuation Systems has issued Service Bulletin 47147-27-18,
dated February 17, 2012.
The actions described in this service information are intended to
correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This Proposed AD

This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.

Costs of Compliance

Based on the service information, we estimate that this proposed AD
would affect about 30 products of U.S. registry. We also estimate that
it would take about 6 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $85 per
work-hour. Based on these figures, we estimate the cost of the proposed
AD on U.S. operators to be $15,300, or $510 per product.
In addition, we estimate that any necessary follow-on actions would
take about 13 work-hours and require parts costing up to $722,556 for a
cost of up to $723,661 per product. We have no way of determining the
number of products that may need these actions.

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. ``Subtitle VII: Aviation
Programs,'' describes in more detail the scope of the Agency's
authority.
We are issuing this rulemaking under the authority described in
``Subtitle VII, Part A, Subpart III, Section 44701: General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.

Regulatory Findings

We determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would not
have a substantial direct effect on the States, on the relationship
between the national Government and the States, or on the distribution
of power and responsibilities among the various levels of government.
For the reasons discussed above, I certify this proposed
regulation:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
2. Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979);
3. Will not affect intrastate aviation in Alaska; and
4. Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.
